Please ask for them to run what is called a Urovysion Urine Test. I , two of these tests wtihin a 6mos time period. I, too, had atypical cells + blood as you describe and had two cystoscopes, and IVP w/constrast x-ray as well as a CT Scan w/o contrast and the bottom
Turns out my atypical cells were Atypical Inflammatory cells and not atypical cancer cells. All the other tests ruled out all the big Cancer stuff, too.
A Urovysion urine test is a DNA test and takes about 7 days to get an answer and the answer is only two things Cancer or Not Cancer ....... bladder cancer is what it looks for. An IVP w/constrast X-ray will look @ the entire system and the CT Scan w/o constrast will show kidney stones.
The test was covered fully by my insurance.
Bottom line for me. They found kidney stones moving around in my kidneys which were chaning the cells and causing the blood.

Sorry on the typos .. but in a nutshell the answer is yes, they can inflammatory cells.
Might you have a urinary tract infection that isn't showing positive? That is how all mine started 3yrs ago ... once they got me on antibotic all my symptoms went away except the blood and atypical cells but I gained the weight back and my knees/ankles stopped hurting.
I lost 10lbs in a week from it.
